My AC7260 wireless adapter crashes sporadically since updating to Win10 Anniversary update. At least it began to occur around that time and no other changes were made to the system. Previous to that the system was running fine for 1+ year.
When the crash happens I lose wireless network connectivity. I am unable to disable/re-enable via Device Manager because it hangs. Sometimes I am unable to Restart or Shutdown Windows. When this happens either option displays the 'working' circle showing Restarting or Shutting Down indefinitely. In all cases to restore connectivity I must hard shutdown the machine using the power button.
If the crash happens and I leave the machine long enough, Bluetooth served by the AC7260 is also taken down rendering my bluetooth mouse and keyboard unresponsive.
I am able to see indicative events in the Event Viewer that state the AC7260 adapter is beginning to restart itself. These events are always logged upon failure event.
I am running a Lenovo Tiny M desktop. I have attached output from SSU, an extract of the relevant Event Viewer entries and screen shots of the driver versions.
I have tried
1- Rolling back drivers one version at a time, opting to remove the device driver from the system upon rollback. Leaving the system on each driver version for a few days to observe. In all cases the crash reproduces itself excep..
2- ... when rolling back all the way to 22-Feb-2015 (220.127.116.11) which worked for a few months but recently the issue reoccured.
3- I tried installing the latest 5-Apr-2017 (18.104.22.168) and experienced the same issue.
4- Checked the recommended settings for 802.11n connectivity.
Please help as this seems to be a driver issue given that nothing has changed on the machine (HW or SW) except for Windows version and Intel AC7260 driver versions.
